Purpose: A head-to-head comparison of efficacy between a cyclin-dependent kinase 4/6 inhibitor plus endocrine therapy (ET) versus combination chemotherapy (CT) has never been reported in patients with clinically aggressive hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer (ABC).
Methods: In this open-label, multicenter, randomized phase II trial, pre/perimenopausal women with clinically aggressive HR+/HER2- ABC were randomly assigned 1:1 to first-line ribociclib (600 mg once daily; 3 weeks on, 1 week off) plus letrozole/anastrozole and goserelin or investigator's choice of combination CT (docetaxel plus capecitabine, paclitaxel plus gemcitabine, or capecitabine plus vinorelbine). The primary end point was progression-free survival (PFS).
The accumulation of plastic waste has urged researchers to develop methods of waste conversion into valuable products, which is fuel. This study aimed to synthesize Ni embedded onto Aceh natural zeolite (Ni/Aceh-zeolite) as a cheap catalyst which could be used in the reforming process to improve the quality of oil produced from polypropylene (PP) pyrolysis. Ni/Aceh-zeolite was synthesized from Ni(NO)·6HO and acid-activated natural zeolite through impregnation and calcination.

The catalyst was prepared by inception wetness and then characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy diffraction X-ray (EDX), and transmission electron microscope (TEM) measurements. The conversion process of glycerol into hydrogen was performed in a fixed-bed microwave-assisted reactor.

Flue gas at coal-fired power stations is one of the main sources for the emissions of SO and mercury metal. Low-cost and sustainable technologies for the removal of SO and mercury from flue gas have become increasingly important nowadays.

Biomass waste is processed through substantial quantities of palm oil extraction. With the reduction in fossil fuels in recent years, it has had an impact on the deterioration of electricity supply at the National and International levels.
